no nothing , i did tried rest it .

still cant find fix for it :(

You need to create a udev configuration file under /etc/udev/rules.d.
Run from the command line (or a SSH) session:

echo 'SUBSYSTEM=="input", ATTRS{name}=="*Touchpad", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""' | sudo tee /etc/udev/rules.d/99-disable-touchpad.rules

then reboot. See if the touchpad still functions after this.

To get back the touchpad, you can remove the file with

sudo rm /etc/udev/rules.d/99-disable-touchpad.rules

followed by a reboot.

@dawnwiener said in 8bitdo adapter with dualshock 4 sony controller - not able to pair device.:

Again, the same error previously reported comes up in the bluetooth configuration screen as an authentication timeout on the 8bitdo.

If you use the 8bitdo dongle, you do not need to use RetroPie's bluetooth menu at all. The pairing happens directly with the dongle, and RetroPie sees the dongle as a wired controller. As @mitu says, you may have better luck trying to pair the controller directly with RetroPie, unless you have a specific need for the 8bitdo dongle.

@mitu
Thank you, removing the call for the ds4drv on /etc/rc.local solved it!

Having looked into this, I edited /opt/retropie/configs/all/retroarch-joypads/Wireless\ Controller.cfg to set input_l2_axis and input_r2_axis and now it works :)

@JuanZt

Just stopped by to thank you. I've used your steps and was able to get my PS4 controller (not original) to work.

@mitu

Yeah, just went through all 4.

Just noticed the light that turns on the ones after connecting the first one is the same that blinks during the bluetooth searching mode.

came across this thread on google searching for a solution to the same problem.
This thread's answer didn't work for me, unfortunately,
but updating the bluetooth driver did work for me.

sudo apt install pi-bluetooth

good luck to anyone else passing by with DS4 connectivity issues!

@mitu Nevermind. That worked. THANK YOU SO MUCH!

After hearing the replies I think I will just power it on with the front button.
Thanks for the replies!

With pcsx-rearmed you can press escape and the menu is black with white monowidth font.

The lr-pcsx-rearmed is retroarch and has a colored menu gui.

I would try installing and trying the other of which you haven't tried.

If it is pcsx-rearmed then the controls will still need to be mapped. Navigating the menu to do this I think is possible with the controller but perhaps easier with the keyboard, as well the escape button needs to be pressed. In the controls menu, assign the buttons, if you press left and right on this screen it will show you Keyboard/Joystick/All binds. And don't forget to save the config when you're done.

You could also try installing the alternate driver, for sixaxis/playstation. The sixaxis helper driver is newer and allows other controllers to sync and use bluetooth.

@webodan I don't think ES reads the list of Audio cards present in the system - the choices you see now are the default choices.
Try using the instruction from the USB Audio FAQ page.

@mitu

Just deleting the ps3 drivers was enough to stop the notice and let me exit the menu without disconnecting the dualshock4. Thanks so much!

I found this thread that seems to contain the answer: https://retropie.org.uk/forum/topic/17650/dualshock-controllers-on-4-4-with-3b/35

This is exactly what I was looking for and it worked, thanks a lot!

@blerkotron i have got the same issue with the analog sticks using a Sixaxis Controller.
Also works fine with jessie.

Something seems to affect the analog Inputs of Sony Controller when using stretch.

@bland328

Actually, in both cases you'd need an external tool. I use xboxdrv, as outlined in the guide I linked to above. Having analog movement available on the stick comes in handy for everything from 'Marble Madness' to 'Spy Hunter'. It's especially nice in 'Centipede', where you're normally all over the place much too quickly with digital controls.

@dankcushions O thanks that's very helpful. I really had my eyes set on the ps1 styled 20th anniversary ds4 controller, but that color layout is only available as a V1..so that could still be an option. (I prefer wired.)
